Withings WS-50 scale-Co2 problems

Does anybody have problems with the Co2 readings on the Withings WS-50 scale ? The iphone app shows no readings at all, and in my web account it only shows the highest possible value of 8000 ppm and the lowest value of 300 ppm, nothing in-between that.
Anybody that have had the same problem and knows what to do about it?


I sent a note to a Withings contact I have via QS Labs and asked for a connection to somebody who might be able to help… Stay tuned.

Thank you.


Hello Pav,

I’m Mathieu from Withings Customer Service.
In order to investigate further could you please give me your scale serial number ?
Here is an article to help you find it : http://withings.zendesk.com/entries/22464797-Where-can-I-find-the-MAC-ID-of-my-Withings-product-

Thank you.

Hi, I am having the exact same problem, can you help? It doesn’t sync air quality at all to my phone. I just see 8000 on the screen of the scale.
